 Exhibit A 

FORM OF 
 SUMMARY OF RIGHTS TO
PURCHASE 
 PREFERRED STOCK 

On June 19, 2012, the Board of Directors (the “Board”) of Navistar International Corporation, a Delaware corporation (the
“Company”), authorized and declared a dividend distribution of one right (a “Right”) for each outstanding share of the common stock of the Company, par value $0.10 per share (the “Common Stock”), to stockholders of
record at the close of business on June 29, 2012 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company a unit consisting of one one-thousandth of a share (a “Unit”) of a newly authorized
series of Junior Participating Preferred Stock, Series A, par value $1.00 per share (the “Preferred Stock”), at a purchase price of $140.00 per Unit, subject to adjustment (the “Purchase Price”). The complete terms of the Rights
are set forth in a Rights Agreement, dated as of June 19, 2012, as amended to date, between the Company and Computershare Inc., successor-in-interest to Computershare Shareowner Services LLC, as Rights Agent (the “Rights Agreement”).

 Rights Certificates; Exercise Period. 

Initially, the Rights will be attached to all shares of Common Stock then outstanding, and no separate rights certificates (“Rights
Certificates”) will be distributed. Subject to certain exceptions specified in the Rights Agreement, the Rights will separate from the Common Stock and a distribution date (a “Distribution Date”) will occur upon the earlier of
(i) 10 business days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired beneficial ownership of twenty percent (20%) or more of the outstanding shares
of Common Stock (the “Stock Acquisition Date”), other than as a result of repurchases of stock by the Company or certain inadvertent actions by certain stockholders or (ii) 10 business days (or such later date as the Board shall
determine) following the commencement of a tender offer or exchange offer that would result in a person or group becoming an Acquiring Person. For purposes of the Rights Agreement, beneficial ownership is defined to include ownership of derivative
securities. 
 Until a Distribution Date, (i) the Rights will be evidenced by the certificates for the Common Stock (or, in the case of
shares reflected on the direct registration system, by the notations in the book-entry account system) and will only be transferable with such Common Stock, (ii) new Common Stock certificates issued after the Record Date will contain a legend
incorporating the Rights Agreement by reference and (iii) the surrender for transfer of any certificates for Common Stock outstanding will also constitute the transfer of the Rights associated with the Common Stock represented by such
certificates. Pursuant to the Rights Agreement, the Company reserves the right to require prior to the occurrence of a Triggering Event (as defined below) that, upon any exercise of Rights, a number of Rights be exercised so that only whole shares
of Preferred Stock will be issued. 
 The Rights are not exercisable until a Distribution Date and will expire at 5:00 P.M., New York City
time on July 1, 2014, unless such date is extended or the Rights are earlier redeemed, exchanged or terminated. 







 As soon as practicable after a Distribution Date, Rights Certificates will be mailed to holders
of record of the Common Stock as of the close of business on a Distribution Date and, thereafter, the separate Rights Certificates alone will represent the Rights. Except as otherwise determined by the Board, only shares of Common Stock issued prior
to a Distribution Date will be issued with Rights. 
 Flip-in Trigger. 

In the event that a person or group of affiliated or associated persons becomes an Acquiring Person, except pursuant to an offer for all
outstanding shares of Common Stock which the independent directors determine to be fair and not inadequate and to otherwise be in the best interests of the Company and its stockholders after receiving advice from one or more investment banking
firms, each holder of a Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right.
Notwithstanding the foregoing, following the occurrence of the event set forth in this paragraph, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person will be null
and void. However, Rights are not exercisable following the occurrence of the event set forth above until such time as the Rights are no longer redeemable by the Company as set forth below. Any person who, together with its affiliates and
associates, beneficially owns 20% or more of the outstanding shares of Common Stock as of the time of first public announcement of the Rights Agreement (an “Exempt Person”) shall not be deemed an Acquiring Person, but only for so long as
such person, together with its affiliates and associates, does not, while such person is an Exempt Person, become the Beneficial Owner of a higher percentage of the shares of Common Stock then outstanding (other than as a result of a reduction in
the number of shares of Common Stock outstanding due to the repurchase of Common Stock by the Company (or any Subsidiary of the Company, any employee benefit plan of the Company or any Subsidiary of the Company, or any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such plan)) as compared to the percentage of shares of Common Stock outstanding Beneficially Owned by such Exempt Person as of the Exempt Time. 

Flip-over Trigger. 
 In
the event that, at any time following the Stock Acquisition Date, (i) the Company engages in a merger or other business combination transaction in which the Company is not the surviving corporation, (ii) the Company engages in a merger or
other business combination transaction in which the Company is the surviving corporation and the Common Stock of the Company is changed or exchanged, or (iii) 50% or more of the Company’s assets, cash flow or earning power is sold or
transferred, each holder of a Right (except Rights which have previously been voided as set forth above) shall thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise
price of the Right. The events set forth in this paragraph and in the preceding paragraph are referred to as the “Triggering Events.” 

Exchange Feature. 
 At any
time after a person becomes an Acquiring Person and prior to the acquisition by such person or group of fifty percent (50%) or more of the outstanding Common Stock, the 







 
Board may exchange the Rights (other than Rights owned by such person or group which have become null and void), in whole or in part, at an exchange ratio of one share of Common Stock, or one
one-thousandth of a share of Preferred Stock (or of a share of a class or series of the Company’s preferred stock having equivalent rights, preferences and privileges), per Right (subject to adjustment). 

Equitable Adjustments. 

The Purchase Price payable, and the number of Units of Preferred Stock or other securities or property issuable, upon exercise of the Rights
are subject to adjustment from time to time to prevent dilution (i) in the event of a dividend on the Preferred Stock payable in shares of Preferred Stock, a subdivision or split of outstanding shares of Preferred Stock, a combination or
consolidation of Preferred Stock into a smaller number of shares through a reverse stock split or otherwise, or reclassification of the Preferred Stock, (ii) if holders of the Preferred Stock are granted certain rights, options or warrants to
subscribe for Preferred Stock or convertible securities at less than the current market price of the Preferred Stock, or (iii) upon the distribution to holders of the Preferred Stock of cash (excluding regular quarterly cash dividends), assets,
evidences of indebtedness or of subscription rights or warrants (other than those referred to above). 
 With certain exceptions, no
adjustment in the Purchase Price will be required until cumulative adjustments amount to at least 1% of the Purchase Price. No fractional Units will be issued and, in lieu thereof, an adjustment in cash will be made based on the market price of the
Preferred Stock on the last trading date prior to the date of exercise. 
 Redemption Rights. 

At any time until ten business days following the Stock Acquisition Date, the Company may redeem the Rights in whole, but not in part, at a
price of $0.001 per Right (payable in cash, Common Stock or other consideration deemed appropriate by the Board). Immediately upon the action of the Board ordering redemption of the Rights, the Rights will terminate and the only right of the holders
of Rights will be to receive the $0.001 redemption price. 
 Miscellaneous. 

Until a Right is exercised, the holder thereof, as such, will have no separate rights as a stockholder of the Company, including, without
limitation, the right to vote or to receive dividends in respect of Rights. While the distribution of the Rights will not be taxable to stockholders or to the Company, stockholders may, depending upon the circumstances, recognize taxable income in
the event that the Rights become exercisable for Common Stock (or other consideration) of the Company or for common stock of the acquiring company or in the event of the redemption of the Rights as set forth above. 

Amendment. 
 Any of the
provisions of the Rights Agreement may be amended by the Board prior to a Distribution Date. After a Distribution Date, the provisions of the Rights Agreement may be amended by the Board in order to cure any ambiguity, to make changes which do not
adversely affect the interests of holders of Rights, or to shorten or lengthen any time period under the Rights Agreement. Notwithstanding the foregoing, no amendment may be made (other than to cure any ambiguity) at a time when the Rights are not
redeemable. 







 Anti-Takeover Effects. 

The Rights may have certain anti-takeover effects. The Rights may cause substantial dilution to any person or group that attempts to acquire
the Company without the approval of the Board. As a result, the overall effect of the Rights may be to render more difficult or discourage a merger, tender offer or other business combination involving the Company that is not supported by the Board.

 A copy of the Rights Agreement has been filed with the Securities and Exchange Commission as an Exhibit to a Registration Statement on
Form 8-A or a Current Report on Form 8-K. A copy of the Rights Agreement is available free of charge from the Company. This summary description of the Rights does not purport to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is incorporated herein by reference.
